SLURRY ANALYTICAL SYSTEM

Quantitative Evaluation of LIB Electrode Slurry

NEW

Analytical Software SA2634 empowers battery researchers and quality assurance teams to objectively quantify the conductivity of lithium-ion battery (LiB) slurries. By providing clear metrics like DCR, Rratio, and Uniformity, it helps optimize R&D processes and production efficiency, enabling faster identification of high-performing slurries without relying on subjective assessments. This leads to superior electrode sheets and cells, reducing development time and improving overall battery yield.

Slurry Evaluation for Improving the Quality of Cells and Electrode Sheets

Enhancing lithium-ion battery performance and yield starts with high-quality electrode sheets, which depend on optimized upstream slurry processes.
SA2634 enables quantitative evaluation of slurry dispersion and conductivity — key factors influenced by material properties, formulation, mixing methods, and kneading time. This approach is based on quantitative science and provides researchers and QA managers with data-driven insights to refine processes, shortening development cycles and ensuring consistent battery quality.

From powder and solvent to final electrode sheet, numerous parameters interact. SA2634 allows you to measure and quantify each stage's state, identifying issues early to prevent defects in the LiB cell.

Evaluation in Small Quantities and Under Real-World Conditions

Assess cathode/anode slurries, conductive pastes, or CNT dispersions with as little as 1 mL — no pretreatment required.
This efficiency accelerates your research by enabling rapid hypothesis testing and verification, minimizing waste while delivering reliable results on dispersion and conductive networks.

Impedance Measurement

The dedicated electrode cell and test fixture minimize measurement noise for highly reproducible impedance data.
SA2634-controlled sweeps take about one minute, capturing slurry state with minimal change during analysis — ideal for dynamic materials in battery research.

Equivalent Circuit Analysis

SA2634 automates complex equivalent circuit creation and initial value setting, handling up to 1000 files at once.
This streamlines batch processing for efficient comparisons, turning raw impedance data into meaningful evaluations without deep expertise in analysis techniques.

Quantitative Indexing

The three indicators, "DCR," "Rratio," and "Uniformity," are derived from the analysis results. These indicators enable quantitative evaluation and also function as a common language between departments and partner companies.
